The NOAA finally discovered that the proper siting of weather stations was important to the accurate determination of temperature.

With increasing urbanization of formerly rural sites, this has much to do with perceived global warming.

The NOAA woke up and launched a study based on a project started by the much maligned weatherman Anthony Watts.

Seems Anthony has more acumen than smug "climatologists" like Hansen, Schmidt, and Mann. He was seeking unbiased data.

"Proximity to buildings and paved surfaces can affect the measured air temperature. When buildings and roadways are constructed near an existing meteorological site, this can affect the long-term temperature trend. Homogenization of the national temperature records is required to account for the effects of urbanization and changes in sensor technology. Homogenization is largely based on statistical techniques, however, and contributes to uncertainty in the measured U.S. surface-temperature record. To provide some physical basis for the ongoing controversy focused on the U.S. surface temperature record, an experiment is being performed to evaluate the effects of artificial heat sources such as buildings and parking lots on air temperature. Air temperature measurements within a grassy field, located at varying distances from artificial heat sources at the edge of the field, are being recorded using both the NOAA US Climate Reference Network methodology and the National Weather Service Maximum Minimum Temperature Sensor system. The effects of the roadways and buildings are quantified by comparing the air temperature measured close to the artificial heat sources to the air temperature measured well-within the grassy field, over 200 m downwind of the artificial heat sources."

Well of course this is true. I went barefoot enough as a child to know that grassy fields were apt to cool off faster. But my knowing it and a scientist being able to site it as fact are two wildly different things. But I was surprised about one thing - are you saying that men's actions create climate change? I haven't been for a while but wasn't climate change something you denied?

Where did you get that idea? I believe the biosphere has warmed in the last 150 or so years as the earth emerged from the Little Ice Age.

But so far, the claim that it is caused by man is scientifically unsubstantiated, the prediction models failed, and the whole anthropogenic warming hypothesis swirling down the porcelain vortex.

In other words,

"All we really know for sure is that man-made activities like constructing buildings and roadways actually does contribute to global warming. The best we can do to attempt to prove otherwise is to introduce 'voodoo meteorology' techniques like homogenization and muddy the water. Then we can say, "See? Nobody really knows for sure."
